This is the best Airbnb stay I've ever booked. Shamp is the architect that designed the building and the interior design. Every aspect of the design is intuitive, allowing a new guest to easily access the building, the unit and the space inside the apartment.
First, the location is perfect for a guest. You are a 5-minute walk to Samyan MRT station, and you can access this through a winding alleyway (very safe, filled with ladies selling noodles). Then you are met with a large intersection and possibly one of Bangkok's best malls (Samyan Mitr). You get a quiet feeling within the apartment, yet you have access to the main street. Also, one of the best congee shops outside Hong Kong is located 9 minutes away and sells congee for 50 baht (Joke Samyan).
Second, the design of the room is impeccable. There is a keycard entrance similar to a hotel. The room has a kitchen area (no stove, but microwave available), a well-designed washroom, then a studio room with a desk and sofa area. The bed is incredibly comfortable, better than when I stayed at Anantara Siam (a 5 Star hotel in Bangkok). The material used for each aspect of the room is of the highest quality, from the wood for the doors and desk to the rug, and especially the sofa.
In conclusion, this is an incredible location and space to stay in for short term and long term stays in Bangkok. Shamp is also a great guy, and he stays in touch with me through Whatsapp for anything I need.
P.S. There is a washing machine; he provides filtered water and water bottles.
